Not bad for a small 5.0 motor eh?
I don't believe you.

SAE-certification is supposed to prevent substantial rating problems, but performance cars are very complicated machines. The true best measure of a car's performance is a trip down the track, not a dyno. Those numbers mean nothing if it can't put them to the pavement.

Dynos aren't very scientific machines. There is a margin for error on the dyno, as well as a margin for error on the drivetrain loss. Combining these really make a wide range for error. That leaves plenty of room for both underrating the vehicle and using a conservative dyno that might not deliver flattering results.

That's affirmative.
